A new two-part Sherlock Holmes adventure, inspired by the stories of Sir Arthur Conan Doyle and written by Bert Coules. starring Clive Merrison as Sherlock Holmes and Andrew Sachs as Dr John Watson Featuring James Laurenson as Mycroft Holmes Part 2: the shocking truth behind the mystery of the politician, the lighthouse and the trained cormorant is finally revealed. In his accounts of the career of his friend Sherlock Holmes, Dr. Watson often makes passing reference to a mystery which his creator, Sir Arthur Conan Doyle, never wrote about in full. Bert Coules, the chief writer behind BBC Radio 4's celebrated dramatisations of the complete Sherlock Holmes canon of fifty-six short stories and four novels, once again takes up the pen where Sir Arthur left off. This is what Holmes buffs call a 'canonical pastiche': a new story written faithfully in the style of the original. It brings to seventy-five the number of times Clive Merrison has played Sherlock Homes on BBC Radio 4. Cast: Sherlock Holmes ..... Clive Merrison Dr John Watson .....
